Background Enuresis is a health problem frequently encountered in childhood. This condition is most likely a symptom of psychological stress, although physiological causes, should not be ruled out. In general, the causes of bedwetting are related to anxiety, life stress, and possibly trauma (chronic illness), both inside and outside the home.

Objectives The aim of our study was to evaluate the prevalence of nocturnal enuresis in children with juvenile idiopathic arthritis.

Methods Forty seven children with juvenile idiopathic arthritis (JIA) and 47 healthy controls were included in a cross-sectional study. The diagnosis of JIA was made according to the criteria of the International League of Association of Rheumatology (ILAR). Data was collected with a questionnaire created by the researchers. Diagnosis of enuresis considered nocturnal voiding twice a week for at least three consecutive months.

Results Forty seven children with JIA were included (28 male, 19 female); the median of age of the patients was 12 [5-16] years. The prevalence of the children having a diagnosis of enuresis was of 8 (17%) versus 2(4.3%) in healthy controls (p=0.04). This enuresis was primary in 62.5% of cases and 50% of the cases occurred after the installation of the JIA. Indifference was the majority reaction of parents. There was no significant association in our study between the enuresis and parameters of JIA.

Conclusions This study suggests that bedwetting is common in children with JIA compared to controls, although it is related to the parameters of the disease.
